Actually my problem is that only a minority knows the original meaning of "goatse", old inside jokes are hard to preserve...

A good name must be easy to remember... (also in the sense that it doesn't cause unease)!

Names like Saturn or Propeller or Biplane for =( )= are much better to understand for someone who only safesearches at google.

If someone wants a joking a reference, one may call it NSFW-Operator... ;-)
